Novel synthesis of N-unsubsdtituted imidazoles using N-trimethylsilylimines
摘要:
Cycloaddition of N-trimethylsilylimines 3 with the lithiotosylmethylisocyanates 4 is described. This provides a novel synthesis of 4-substituted and 4,5-disubstituted imidazoles from easily accessible aldehydes or organolithium reagents, under mild conditions and in a one-pot operation.
